=VLOOKUP(A310,[sls.xls]Detail!$A$271:$A$296,17)
Workbook "CD" has the name COVER in A310 and a blank cell next to it
in column B (where I have placed the formula)
Another workbook (sls) column A has the name COVER, but provides the
amount for the cover between the rows of 271 to 296 in column 17.
what am I missing in order to get results?
Thanks for any help you may provide

Add "FALSE" to the formula as in
=VLOOKUP(A310,[sls.xls]Detail!$A$271:$A$296,17,FALSE)
